AUTOMATIC PRINTING-CAMERA.

Patented Aug. 1, 1916.

Application filed July 1a, 1915. Serial No. 40,301.

To all whom it may concern:

Be it known that I, ALMOND R. RANOIER, a citizen of the United States, residing at Lima,-in the county of Livingston and State of New York, have invented certain new and useful Improvements in Automatic Printing- Cameras; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and. use the same.

This invention relates to photographic apparatus and has special reference to a device which is preferably termed an automatic printing camera.

One principal object of the invention is to provide a camera of this description wherein a device is employed which exactly shows the time of each exposure of the printing paper used to produce the usual positive, the device being of improved construction.

A second object of this invention is to provide im roved means for regulating the cut ting o of the actinic light rays from the sensitized paper until the proper time arrives for its exposure to such rays.

A third object of this invention is to provide improved means for holding the sensitized paper firmly against the photographic negative.

A fourth object of this invention is to provide improved means whereby the operation of the device will wind the clock attached thereto whenever the device is operated.

With the above and other ob]ects in view the invention consists in general of certain novel arrangements of details and combinations of parts hereinafter specifically described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like char acters of reference indicate like parts in the several views, and Figure 1 is an elevation of the operators end of the device. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a plan view of a portion of the operators end of the device with the tops removed. Fig. 1 is a detail section on the line 44 of Fig. 1 showing the spaced tension means. Fig. 5 is a detail section on a part of the line 55 of Fig. 1 showing the shutter operating and releasing mechanlsm.

In the present embodiment of the invention there is illustrated a box casing having sides 10 and a front or operators end 11 provided with an opening 12. The other end of the casing is intended to face an opening in alight proof screen and is provided with guides 13-a-rranged on the inner surfaces of the sides lO so that a frame 14 carrying a diffusion screen 15 may be slid vertically into and out of position in these guides. This diffusion screen is used for the purpose of diffusing the light admitted to the sensitized paper so that an even distribution of actinic rays is produced.

Surrounding the opening 12 is a frame 16 to the bottom of which is hinged as at 17 a presser plate consisting of a lower member 18 having an upper member 19 hinged thereto, as at 20. Each of these members is provided with a felt or other resilient cushion, as indicated at 21, arranged to press the sensitized paper 22 into position against the negative 23 and press the latter firmly against the frame, it being understood that the frame is rabbeted to receive the plate and sensitized paper as clearly shown in the drawings.

Atpresent it is to be understood that proper means are provided for forcing the parts 18 and 19 into position but the preferable means employed will be nowdescribed. Across the lower'member 18 of the presser plate is disposed a guide member in the form of a plate 24 hinged to the member 18 at its bottom edge as at 25. This plate is provided with grooved edges 26 for the receptionof the sides of a sliding frame 27 which is hinged to the member 19--at 28.

Across the upper part of the plate 24 extends a'bar 29 provided at its ends with screw eyes 30 to each of which is secured one end of a tension spring 31. These springs pass through openings 32 in the end of the box and are led around rollers 33 mounted in the box. Extending through the end of the box below the openings 32 are tension screws 34 provided with butterfly nuts 35 and connected to the remaining ends of the springs 31 by links 36. Thus by operating the but terfiy nuts 35 the tensions of the springs 31 may be regulated and this regulates the pressure of the plate 24 against the member 18 which in turn regulates the pressure of the member 18 toward the negative. Furthermore these springs also serve, through the medium of the slide frame 27 to force the member 19 toward the negative when the frame is slid upward in the plate 24..

In order to move the member 19 outward an afford access to the upper part of the negative and sensitized paper, this member is provided with a bar 37 extending across its upper part and having a finger loop 38 positioned intermediate its ends. By pulling outward and downward on this loop the member 19 will revolve about the axis of the hinges .20 while the slide frame 27 and plate 24 will assume the position shown in Fig. 4. When in this position the position of the member 19 is so nearly at a right angle to the slide that the friction between the slide and plate 21 is suliicient to lock the member 19 against closing without manual intervention.

Attached to one end of a bar 37 on the member 19 is one end of a spring 39 which passes through an opening 40 in the operators end of the box and runs over a roller 11. To the remaining end of this spring 39 is attached a strand 41 which runs over a roller 42 mounted on a lever 13 pivoted to a partition +3 arranged to form a pocket for one of the springs 31. A second partition 41 is fixed in the box in spaced relation to the partition 43 and serves to cut oil all light entering through the opening 40. The remaining end of the strand 41 is attached to a pin it projecting from one side of a screen 45 opaque to all actinic rays, the screen being hinged to the floor of the box as at 46 so that it can be raised to cut off the actinic rays when the member 19 is pulled open and the strand drawn upon.

In order to drop the screen 45 when the member 19 is closed the lower end of the lever 43 is forked as at 46* and straddles the pin 11. To the lever 13 is pivoted an arm -27 the free end of which is well weighted by lead weights 18. This arm is provided with hook 49 at its end and is arranged to hook over a pin 50 on the wheel 41. Pivoted between the partitions 13 and 4-1 is a sleeve 51 wherein slides a plunger 52 which is pivoted to the bar 37 so that as the member 19 swings in and out the plunger also moves in and out and thus engages the arm 47 and lifts the hook 49 clear of the pin 50, at the same time, by frictional engagement with the arm 47, giving the lever arm 43 an initial rearward movement so that the actinic screen 45 falls. It is to be noted that this falling movement is begun only a i'tcr the member 19 is closed and is resisted by air friction or resistance on its lower side so that it is gradual.

' To the bar is attached a flexible strand 58 which extends into the casing above a horitzontal partition 54 and around guide pulleys 55 and 56 and has its end wrapp around a disk 57 and connected thereto so that @the movement outward of the member 19 rotates this disk. To prevent shock and too great movement of the disk 57 a coil spring 58 is interposed, as shown, between the ends of the strand 53.. Wrapped around the disk and secured thereto is one end of a second strand 59 led through a guide 60 to a .clock winding pulley 61. fixed on the winding arbor (32 of a clock work mechanism 63 the (lGttlllgQf which are not deemed necessary to enter into at this time but which has a winding arbor of that type which revolves when the clock runs down. By this latter means the opening of the member 19 effects winding of the clock while the unwinding or running down of the clock rotates the disk 57 and tensions the strand 53 after the member 19 is closed.

In the front or operators end of the box is an arcuate slot 64 having a scale 65 concentric therewith, the scale being laid in suitable divisions such as seconds and fractions of seconds, a ointer 66 being attached to the disk 59 and projecting through the slot to indicate on the scale the movement of the disk.

The apparatus thus described is used as follows :The box or casing being positioned, as previously described, with its diffusion screen forming a window opening closure, the operator selects the desired negative to be reproduced. He then pulls down on the grip 38 and opens the member 19 after which he opens the member 18 by pulling on the finger grip (57 of a lever 68 connected to the member 18 at (i and pivoted to the front of the box as at 70. He then raises the bar 37 and introduces the negative after which he closes the bar 37 and slips a piece of sensitized paper between the negative and members 18 and 19. The outward movement or opening of these members 18 and 19 has, as described, closed the actinic shutter or screen 45 and wound the clock. \Vhen the members 18 and 19 are closed the clock starts, winding tension on the spring being released and at the same time the actinic screen opens. The operator now observes the pointer 66 and when this pointer has moved from 0 to the required time indication on the scale, again opens the member 19, which rewinds, resets, and stops the clock and at the same time closes the actinic screen. He then removes the ex posed sensitized paper and if desired, replaces it with another piece. This operation is repeated until the required number of exposures have been made from a given negative after which this negative may be removed and another substituted.

There has thus been provided a highly eificient device of the kind described and for the purpose specified.
